The gang is having fun with their old friends who are now a music group. They are ready to sing a new song based on an ancient voodoo chant but they also bring back a long dead ancient shaman who plans to turn them into zombies.
The gang is attending the concert of their old friend, Alex Super, who has become the lead singer of a famous band. During one of the band's new songs, titled "Mamba Wamba", an ancient shaman appears, telling them they have violated a sacred chant by playing the song. With a cloud of smoke, he disappears, taking the band’s solo female member Lila. The gang decides to help Super find Lila by heading to Maison Dupree, the plantation Lila grew up on. There, they discover voodoo dolls of all the members of Super, including their manager, Roger.
While they're searching for clues, a zombie appears to chase Shaggy and Scooby. After all of the band members disappear one by one, it's up to the gang to save them, as well as Lila. After a failed attempt at catching Mamba Wamba, the gang decides to split up once more. Shaggy and Scooby are chased by the zombie outside and take refuge in a grass field.
After they lost the zombie, they heard thumping in a nearby log, which they believe is Mamba Wamba inside, but it turned out a frog was inside. They hear the hear voodoo drums in the distance and attempted to run away from them, (with the frog hitch-hiking with them) but ended up on top of a hut. While hiding, they discover they're in Mamba Wamba’s lair, where they see Alex, Ray and Deek being held hostage. They also discover that Lila has in fact been turned into a zombie. Mamba Wamba promises Alex, Ray and Deek the same fate as Lila, unless they sign a parchment vowing to never play the sacred chant again.Alex signs the parchment, just as Scooby and Shaggy give away their hiding places. The frog then steals the parchment with Shaggy, Scooby, Mamba Wamba, the zombie, and Lila pursuing it.
Shaggy and Scooby escaped, giving the parchment to Fred, Daphne and Velma, who recognize it as the final clue. They devise a trap in order to catch Mamba Wamba. After capturing them in a net, the gang calls the police to unveil what's been happening.
It turns out Roger was Mamba Wamba, Lila played herself as a zombie, and the other zombie is an unknown henchman. Both Roger and Lila realized that the song, Mamba Wamba was worth millions. So they devised a scheme to scare the band out of their rights to the money. The paper that Alex signed was actually a legal release with a fake parchment glued above their signatures.
Everyone celebrated by having dinner at the plantation having crawdad gumbo. However the frog ate every drop in the pot, Shaggy then suggests making frog gumbo instead which scares the frog out, but came back after Shaggy assured him he was only kidding, and that they prefer pizza anyway.
